| Abstract |
A multi-scale higher-order continuum model is developed for the investigation of the mechanical properties and buckling behaviors of boron nitride nanotubes (BNNTs) at finite temperature. A meshless local Petrov-Galerkin (MLPG) computational scheme is constructed based on the proposed hyper-elastic constitutive model to simulate the deformations of BNNTs. The Young's modulus, shear modulus and Poisson's ratio of BNNTs are studied. The buckling patterns of BNNTs subjected to compression, bending and twisting at finite temperature are simulated, respectively. The results are in good agreement with those obtained by other methods. |
